SEAM FOR SEWED ARTICLES.

Specification of Letters Patent.

Patented Jan. 21, 1908.

To all whom "it may concern: 7

Be it known that 1, JOHN P. Wars, a citizen of the United States, residing in Brooklyn, county of Kings, and State-of New-York, haveinvented a new and useful Improvement in Seams for Sewed Articles, of which i vmain-loop,v1z., between said loops and the the following is a description.

This inveption'relates to seams for sewed articles, and has special reference to seams which are made over the edge, or-edges, of pieces of fabric.

An object of my invention is to produce a seam for sewed articles containing a plurality of threads and concatenated into a chainstitch which will not rip, run, or pull out.

Another object of my invention is to pro-' vide a chain'stitch for overedging which cannot be ripped, drawn, or pulled out, and which will produce, or provide, an effective and ornamental selvage, binding, edging, or finish for fabrics.

With these objects in View, my invention consists in the features and combinations hereinafter described and claimed.

In the drawings: Figure l'is a erspective view showing the top and edge 0' two pieces of fabric having a three-thread stitch applied thereto in accordance with my invention; Fig. 2 is a perspective view showing the edge and bottom of two pieces of fabric having my three-thread stitch applied. thereto; Fig. 3 is a view similar to Fig. 1, having a twothread stitch applied thereto in accordance with my invention; and Fig. 4 is a view similar to Fig; 2, showing my two-thread stitch.

1, indicates the fabr.ic,which may be a single piece, or maybe two pieces superposed. 2, indicates the first, or main, thread; 3, the second, or edge, thread; and 4, the third, or locking, thread. i

The main thread is passed down through the fabric at successive points in loop form, thus making a straight line of stitching, and at each of said points forming a main loop 2 which is given a twist or half turn and cai Tied to the edge of the fabric. At this point, a loop 3 of the edge thread is passed up through the main loop 2?, and carried to and on the surface of the fabric into position to be, and is in turn, entered by a succeeding main-loop 2 The main-loop 2*, has passed about one of its strands 2 a' loop 4*, of the locking-thread, both strands of,which latter are passed between asucceeding loop 2*, of the main-thread and the fabric. The look-- I ing-thread loop e in upassing around the strand 2*, of a main-loop, 1s also given atwist, orhalf-turn; that is to say, after having engaged the first main-loop, the strand 4}, of locking thread passes over a second main-loop, then around and over a third loop, entering the same from below, passes around the strand 2 thereof, between it and the fabric, and then back under and crossing its own strand and over the third main-loop. This manipulation of the threads completes a stitch-making cycle.

The amount of tension applied to. the respective threads determines the character and general appearance of. the seam; that is to say, the main loop 2*, may be drawn, by a heavy tension on the second, or edge thread, completely to the upper edge 1, of the fabric, or over said edge, or to any point between the two edges 1, and l or to any position on the bottom of the fabric. This is also true with regard to the second, or edge, thread, its disposition on the surface, bottom, or edge of thc'fabric being dependent upon the degree of tension applied to the main thread. Furthermore, the condition and appearance of the main loops, on the bottom of the work, depends upon the degree of tension applied to the third or locking thread; that is to say, if the tension on the locking thread is heavy,

the strand 2, of the main loop 2, will be' very much .distorted, as shown on the right in Fig. 2, while if the said tension be lighter the said strand will be distorted to a lesser degree, as shown by other main loops on the left in Fig. 2. Hence, it will ,be seen that the appearance and general effect of the seam can be greatly varied.

In the above description, I have disclosed a seam consisting of three threads; but, a seam of the same nature and having the same characteristics and general appearance may be made of two theads. Such a seam is shown in Figs. 3 and 4, and therein the seam is composed of only a main-thread 5, and a locking thread 6. The loops 5*, of the main thread are passed down through the fabric, given a twist, or half turn, carried up over the edge of the fabric and into position to be, and are, entered by a second, or succeeding, of the main thread. The locking thread oops 6?,are manipulated and caused to concatenate with the loops of the main-'- I 'loops of the main thread. andfalso partially threadin exactly the manner described in connectlon with the three-thread stitchof Figs. 1 and 2.

It will be. noted that on both facesof the work, along the line of the needle punctures, there is a bead or rib formed, that on one face, Fig. 1, being produced by the continuousrun of the thread 2 from puncture to puncture, constituting a straight line of stitching combined with the thread of the loop of the overedge thread 3, the two thicknesses of thread thus being raised considerably above the face of the work; while that on the other face of the work, Fig. 2, being formed by the'twist of the loop of the thread 1 at the punctures and which places one strand-upon the other, thusraising the threads considerably above the face of the work. The beading onthe face of the work in Fig. 2 is materially accentuated by the locking-thread which. runsunder the surrounds the, latter at theyneedle punctures. Thus it will be seen that an artificial sel v'age is produced which has substantially three lines of beading or rib elfects, one on each face of the work and the other onthe edge thereof. 'In. theexagge'rated views given in tween the loo of'main thread and the work,v

the drawings this beaded eifect not so apparent, but it is obvious to any one skilled in the art that when the stitches are close toe gether, causing the threads, to thoroughly cover the edge of the work, the lilies of head ing'and finish become quite prominent. Hence, the half-turn or twist given the loops of the main-thread produces. a wearing rib and finish to the stitch as well as aidsin pro-t ducing an ornamental'ffect." The half-turn,

or'twist given the locking-thread tends to the 'sameresult, in that by passing one of its strands across another and both of them bethread may be drawn upon. Moreover, it

will be clear that I have produced a seam which is highly ornamental and whose or- .nate effect has a large range of variation; also and connected with a succe .signed my name in the H n a seam which, as a binding n'd finish for the edges of fabric and as an 'tificial selvage, has no equal. 7 f

Having thus described y invention what I claim and desireto obtain'by better-s Pate.

cut is: u v

A seam for sewed articles comprising the fabric and a plurality of-threads, one of thexlatter being passed down through the fabric'in loop form, thenfgivena half turn or twist and carried across one. ace of the fabric loop ofthe same thread; and another "of sai "threads, in the form of a half-turned or twisted loop, be-

ing engaged with a strand ofsaid first loo of the first thread andpassingbetweenithe' a ric'and sa d suhceeding loop of the'first'thread.

-2. A seam forsewedfarticlescomprising the fabricanda pluralit'y of threads, one of the latter being passed-down" through the.

fabric in loop form,-then.gi'venfa half turn or twist. and carried. across'one face of the fabric and connectedwi'th a' succeedin loop of the same thread by a loop eta secon' I thread"; and

a third thread, 'in'the-formiof-ahalf turned or loop-of the firstthread. j 2

A sea the fabric and-a pluralit iof=threads, said? seam. being characterized y'h'avi'ng a'line of' straight stitching on one face of the fabricconj catenated with half'turned orjtwisted loops extending from the other face of the fabrictwisted loop, being engaged with Ia'strand fofthesaid'first loop of thefirst threadand pass- 111g. between the fabric and said succeeding- I' and more or less across the edge thereof, and

a locking-thread surrounding and connecting respectively one strand of each of said loops.

'4. A seam for.,sewedf articles comprising the fabric and a plurality of threads, said seam being characterized by having a straight line of stitching on one face of the fabric and two series of concatenated half-turned or twisted loops on'the'other face of the fabric, "certain ofsaid loops being carried more or less across the edge of the work and connected Withthe straight line of stitches.

" In testimony whereof I have hereunto presence of two subscribing witnesses.
